Exercise 3. Suppose you are sending a large file from your laptop to another host over a TCP connection and assume that the connection have no loss. Round-trip times for this problem is constant 1 RTT) (a) Suppose TCP uses slow start and then uses Additive-Increase and Multiplicative-Decrease (AIMD) for its congestion control after cwnd reaches 16 MSS. Assuming cwnd increases by 1 MSS every time a ACK is received during the slow start and by 1 MSS every time a batch of ACKs is received during the AIMD how long does it take for cund to increase up to 20 MSS from 1 MSS? (b) What is the average throughput of this connection (in terms of MSS and RTT) from time 0 up to time t = 10 RTT
